Not so obvious benefits of immersion cooling in your data center

tin_whiskers

Giving your servers a bath in an immersion cooling environment has some immediate benefits that we’d like to expose in this short article. There’s some obvious ones that we’ve mentioned many times like making your data center greener and slashing operation costs, but today we’re going to talk about some not so obvious benefits:

  • Silent Operation: this one is straight-forward. All fans on the servers are usually removed before placing them into their dielectric bath. Of course even if they had fans, by placing them in a fluid we’re immediately silencing them. It might not sound as a great benefit, but for those of us that’ve worked for hours in a row with servers inside a server room, we’ve felt the pain. Its very impressive to walk into a immersion cooling data center room with hundreds or thousands of kW’s of IT hardware submerged and not hear a thing. The dual pump system is just as silent, so you won’t be hearing them either.

Data center liquid immersion cooling with adiabatic cooling towers

What is Adiabatic Cooling?

Adiabatic cooling is the process of reducing heat through a change in air pressure caused by volume expansion. In nature, adiabatic cooling is often associated with elevation. As seen with cloud formations, an air mass that is heated expands and becomes less dense. Being less dense, it is lighter and rises above a higher-pressure air mass. Having reached areas with less dense air, it further expands, losing energy that was gained, and cooling as it does so. When the cooling air crosses the dew point, moisture in the air accumulates as clouds. With enough moisture and cooling comes precipitation. The principles of adiabatic cooling are also applied to increase humidity in facilities.

What are Adiabatic Cooling Towers and why are they used in Data Centers?

Data center cooling methods

In this post we’re going to cover some of the most common cooling solutions for data centers and also some new trends. Over the years, data centers have seen substantial changes in how server room cooling was managed. Years back (say 15-20 years back), nobody really cared how much power was consumed to actually cool a server room. Its just something that had to be done and the cooler the better. Then all of a sudden somebody started talking about PUE’s (Power Usage Effectiveness) and they discovered that most of the data centers had PUE’s of 2.5 or even 3. Crazy times…!
